Java polymorphism and exception handling--hands-on brain

Write a program that requires the user to enter an integer at run time, representing the exam results of a course, followed by a "fail", "Pass", "Medium", "good", "excellent" conclusion.

Requires that the program be robust enough that it does not crash regardless of what the user enters.

Import java.util.*;

public class Mark {

public static void Main (string[] args)

{

Scanner SC =new Scanner (system.in);

int score=0;

System.out.print ("Please enter your score:");

Try

{

Score=sc.nextint ();

if (score>=0&&score<=59)

{

SYSTEM.OUT.PRINTLN ("fail");

}

if (score>=60&&score<=69)

{

SYSTEM.OUT.PRINTLN ("Pass");

}

if (score>=70&&score<=79)

{

System.out.println ("Medium");

}

if (score>=80&&score<=89)

{

System.out.println ("Liang");

}

if (score>=90&&score<=100)

{

System.out.println ("excellent");

}

if (score<0| | SCORE>100)

{

System.out.println ("The number entered is too large or too small");

}

Else

{

System.out.println ("");

}

}

catch (Exception e)

{

System.out.println ("Please enter the correct number:");

}

}

}
